An outer casing of a hot air furnace is represented at I containing theusual rebox crown 2. Just above the crown 2 and dened by the outercasing of the furnace is a hot air distribution chamber 3 in which ismounted an yevaporation open top elongated pan 4. The pan 4 issupportedcentrally, diametrically and horizontally and has connected into one endan overflow pipe 5 which delivers any overflow of water outside thecasing of the furnace and also serves the 'purposeof supporting one endof the pan 4. The other end of said pan 4 is supported by a vbracket 6.The furnace casing has an aperture 'I therein which aperture is closedby fastening a face plate 8 by means of attaching means 9 unto thefurnace casing I. Plate 8 has a relatively small elongated aperture IBin its lower part with the material of said plate dening said apertureproviding a seat portion to receive and support the bracket 6 whichbracket'is inwardly removable from aperture Ill to allow assembly anddisassembly of the pan 4 to and from'the furnace. Overflow pipe 5 isslidable in its opening inthe furnace casing hence the pan 4 can bemoved back and forth in the furnace to allow for assembly or disassemblyof the pan 4. The plate 8 has apertures VII and I2 above the aperture I0withV aperture I2 occurring in a dished portion I3 in plate 8 vwith thematerial of said plate dening said aperture providing a seat portionwhich `seat portion lies in a different vertical plane than the seatportions of the firstV and second apertures. A second plate member I4having Va slot I5 and an aperture IB is` attached to the first plate 8by attaching means iI'I passing through the slotted portion I5 and intothe rst plate 8. The second plate I4 is Vertically adjustable on thefirst plate 8 and the amount of adjustment is limitedby the length ofslot I5. Attaching means I'I vis loosened in adjusting the second plateon the first plate to allow relative movement between the two platesafter which it is tightened to hold the VplatesS 'and I4 inadjusted'position. l' o A thermostat I8 extends into the furnace chamber3 through` the plates 8 and I4 and has connected therewith a waterconduit I9 that extends through plate 8 and discharges into pan 4. Thethermostat I8 rests on the seat portions rdefining apertures I6 and I2in the second and first plates I6 and 8 to provide a two point supportfor the thermostat I8 since apertures I2 andr I6 are spaced apart inview of the dished portion I3 ofplate 8. Y

In Figures 4, 5 and 6 a different species of the invention is shown,with a rstplate 20 to be attached across an aperture ina furnace wall. A

'relatively small elongated aperture 2| Ais. provided in plate 20 toreceive the bracket from a pan in the furnace chamber, as in Figures Yl,2 and 3,

with a second aperture 22 to receive a water conduit and a thirdaperture 23 to receive a thermostat. It is noted that the third aperture23 does not occur in a dished portion of plate 20 as in the previouslydescribed species but is flush with the plate. Asecond plate member 24having a slot 25 in its upper end is adjustably attached to the firstplate by attaching means 26. The second plate 24 is bent so as to haveits lower portion off-set and in effect is in the form of a springfinger. The lower offset portion of the second plate 24Y hasV an openingthere through, and a thermostat 21 4 passes through the opening in thesecond plate and is rigidly attached to the second plate 24 by clampingnuts 28 and 29 carried by the thermostat 21. In mounting the thermostat21 in a furnace chamber, the thermostat 2'I has the second plate mountedthereon first after which the thermostat 21 is passed through opening 23in the rst plate 2B. When the thermostat has been properly adjustedvertically in the furnace chamber; attaching means 26 is tightened andthe thermostat is in place in the furnace chamber. It is noted that thisspecies also provides a two point support for the thermostat and allowsthe same `adjusting features as the previous species.

Figure 6 shows in section a valve member 3B mounted on the end ofthermostat 21. The valve S9 has a Water inlet pipe 36 connected thereto,an opening 3l in the valve, a needle 32 controlling the opening 3! andan outlet pipe 33 leaving the valve 30 and emptying into the pan withinthe "furnace, The needle 32 is rotatably mountedon a bracket 35 attachedto thermostat 21 and sur'- rounding valve 30 for adjusting needle 32 vinopening 3l. Needle 32 is threaded into a' gasket 34 in valve member 30which gasket provides a seal around the needle. As the thermostatexpands and contracts, it movesv Valve 30 away or towards needle 32 toopen or restrictfu-rther the opening 3i yto control the flow of water to-outlet 33;- The gasket 34 has a sliding iit with valve 30 and stillmaintains the seal eventhough allowing movement of the valve 30 withrelation to the needle.

While the invention has beenY described in connection with severalspeci'c'embodimentait is to be understood that the words which have beenused are words of description rather than limitation, and that practiceofthe invention withinthe scope of the appended claims may beresorted'to without departing from the true scope of the 'invention inall its aspects.
